Overview

Crystal clear, full-range sound.

The Peavey SP 4 speaker has an ingenious design that improves low-end performance, and produces clearer sound, in the high frequency range. This quasi three-way enclosure has 2 - 15" Peavey Black Widow speakers, capable of handling up to 4000W peak power, and have field replaceable baskets for quick, easy repair. It has a much more efficient crossover, that directs low frequencies to both woofers, while limiting midrange frequencies to only the top woofer. An RX22 titanium driver that is ferrofluid cooled for maximum tweeter performance, and longevity, handles upper-mids, and high frequencies. Peavey's exclusive Quadratic Throat Waveguide technology actually reduces horn distortion, and aims sound directly at the audience, not over their heads. The aspen hardwood plywood enclosure uses extensive internal bracing that produces tighter bass response. It's finished in the durable Hammertex, and has heavy-duty handles and kick back wheels for easy transportation.

Made in the USA.
